<p>Several vulnerabilities were discovered in Heimdal, an implementation of
Kerberos 5 that aims to be compatible with MIT Kerberos.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-16860">CVE-2018-16860</a>
<p>Isaac Boukris and Andrew Bartlett discovered that Heimdal was
susceptible to man-in-the-middle attacks caused by incomplete
checksum validation. Details on the issue can be found in the Samba
advisory at <a href="https://www.samba.org/samba/security/CVE-2018-16860.html">\
https://www.samba.org/samba/security/CVE-2018-16860.html</a>.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-12098">CVE-2019-12098</a>
<p>It was discovered that failure of verification of the PA-PKINIT-KX key
exchange client-side could permit to perform man-in-the-middle attack.</p></li>
</ul>
<p>For the stable distribution (stretch), these problems have been fixed in
version 7.1.0+dfsg-13+deb9u3.</p>
<p>We recommend that you upgrade your heimdal packages.</p>
